OPTIC is a highly advanced Gas Chromatograph multi mode inlet system with sophisticated temperature and
gas flow control that can be used for the most demanding GC analyses. The current version OPTIC-4 can be used
for hot injections, cold injections, large volume, on-column injections, in liner derivatisation,
thermal desorbtion, pyrolysis and more. Go to OPTIC page...

GL Sciences GC/GCMS columns made in Japan.

GL Sciences InertCap GC and GCMS Columns are designed and manufactured in Japan and
offer the lowest bleed levels, the best inertness for acids/bases/mixed functional compounds,
and the tightest column-to-column reproducibility.

GL Sciences LC columns

GL Sciences Inertsil, InertSustain and MonoCap Columns are designed and manufactured in Japan and
offer the lowest bleed levels, the best inertness for acids/bases/mixed functional compounds,
and the tightest column-to-column reproducibility.

GL Sciences has a wide range of sample preparation products that is produced in Japan. The available products are based on our in house technologies like monolithic technology, deactivation and chemical bonding.

InertSustain C18 Wide pH Column
Generally, silica based columns are mechanically stable and provide high efficiencies, however, they cannot be used under alkaline conditions and their residual silanol groups tend to adsorb organic bases.

InertSustain C18 employs a radically new type of silica, in which the surface of the silica is uniquely modified, enabling precise control of the silica properties. InertSustain C18 inherits the advantages of all the current Inertsil HPLC columns (e.g., extremely low operating back pressure, superior inertness to typically any analytes, high efficiency and compatibility with a wide range of solvents), but now can be used for wide pH analysis with consistent performance from column to column and lot to lot..

By choosing InertSustain, you can be assured that you are using one of the most trusted, popular, and enduring HPLC columns in the history of HPLC.
